“…O primeiro padrão de transcorrência NE-SW (destral) possui a mesma orientação estrutural do Escudo Catarinense (Fig. 1) e do substrato da Bacia do Paraná em Santa Catarina (Jacques et al, 2014), sugerindo tratar-se da reativação de estruturas pré-cambrianas no Fanerozoico, particularmente entre o Neocretáceo e o Paleógeno, conforme tem sido postulado por vários autores (Zalán et al, 1987(Zalán et al, , 1990Ferreira & Almeida 1989;Almeida, 2005;Roldan et al, 2010, dentre outros).…”

“…Estudos de correlação estrutural entre dados geofísicos (alinhamentos magnetométricos) e de imagens SRTM (lineamentos), realizados na borda leste da Bacia do Paraná em Santa Catarina e no Escudo Catarinense, mostram claro prolongamento das estruturas dúcteis NE do embasamento no substrato da bacia, bem como a reativação deste padrão estrutural no Fanerozoico (Jacques et al, 2014), particularmente como falhas transcorrentes entre o Neocretáceo e o Paleógeno (Zalán et al, 1987(Zalán et al, , 1990Ferreira & Almeida, 1989;Almeida, 2005;Roldan, 2007;Machado et al, 2012).…”

A análise estrutural de falhas e fraturas realizada em pedreiras de rochas vulcânicas da Formação Serra Geral, Bacia do Paraná, região serrana do Estado do Rio Grande do Sul, permitiu definir quatro famílias principais de falhas: NE-SW a NNE-SSW, WNW-ESE a E-W, N-S e NW-SE (menos expressivas na escala de afloramento). Os lineamentos (392) extraídos de imagens LANDSAT TM7 e do modelo digital de elevação-SRTM, na escala 1:250.000 apresentam uma frequência de estruturas com orientação dominante WNW-ESE (N60-80W), com valores menos expressivos orientados NE-SW (N30- 40E) e NNE-SSW, N0-10E). As falhas NE-SW e E-W acham-se preenchidas por microfibras de carbonatos e óxidos (de ferro e manganês) e mostram o predomínio de cinemática transcorrente destral. Já as falhas N-S e WNW-ESE não são preenchidas por microfibras, e a cinemática das transcorrências é dominantemente sinistral. A relação cronológica entre as famílias de falhas sugere três grupos de falhas transcorrentes: um mais antigo (Eocretáceo), com direção NW e cinemática destral, um intermediário (Neocretáceo ao Paleógeno), com direções N-S a NNE-SSW (destral) e ENE-SSW a E-W (sinistral), e outro mais novo (Paleógeno ao Neógeno), com direções NE-SW (destral) e NW-SE (sinistral).

“…However, the Tijucas and Itajaí-Açu rivers basins share largely similar lithologies as they both drain the Archaean-to Proterozoic-aged igneous (granities) and meta-sedimentary rocks (dominantly gneiss) of the Brusque fold belt (Jacques et al 2014). Intense weathering of this crystalline bedrock has produced a saprolite that is tens of meters thick and supplies large quantities of fine-grained sediment as well as sand and fine gravel to both the Tijucas and Itajaí-Açu rivers.…”

Coastal sedimentation is driven by a combination of wave and tidal energy, sediment supply, and relative sea-level change. During the Holocene, these factors have combined to fill coastal embayments along the headland-dominated coast of Santa Catarina, Brazil. Here, three partially filled basins exhibit marked variability in their sediment sources, wave exposure and resulting stratigraphy and beach morphology. Hydrodynamic modeling highlights the primary roles of sediment supply and wave energy in producing three vastly different basin-fill sequences. The lack of a river source to the Pinheira Strandplain results in a bayfill sequence dominated by shelf-derived sand. Along the open coast of Navegantes, high wave energy removes fine sediments derived from the Itajaí-Açu rivers, producing a sand-dominated sequence. At Tijucas, fed by the much smaller Tijucas River, fronting headlands minimize wave energy, allowing for the accumulation of fluid mud in the shoreface. The result is a basin-fill sequence larger than that at Navegantes, but dominated entirely by mud.

“…The main structural features of the Paraná Basin were recognized using satellite imagery lineaments and fault plane trends (e.g., Soares et al, 1982;Zerfass et al, 2005; Reginato and Strieder, 2006;Strugale et al, 2007;Machado et al, 2012;Nummer et al, 2014;Jacques et al, 2014), geophysical lineaments (e.g., Ferreira, 1982;Ferreira et al, 1989;Quintas, 1995), or isopach maps developed for each sedimentary sequence (e.g., Northfleet et al, 1969;Artur and Soares, 2002). The main findings include regional lineaments, arcs, and flexures ( Fig.…”

Abstract. This paper examines the domes and basins, regional arcs and synclines, and brittle structures of the Paraná Basin flood volcanism to characterize the deformational phases in its Jurassic to Cretaceous history. First-stage fieldwork revealed brittle structures, extensional joints, and strike-slip faults, and second-stage fieldwork investigated the connections of the brittle structures to both open folds and dome-and-basin features. Fault-slip data inversion was performed using two different techniques to distinguish local and remote stress/strain. Geometric and kinematic analyses completed the investigations of the deformation, which characterized two deformational phases for the Jurassic to Cretaceous periods in the Paraná Basin. Both developed under regional bi-directional constrictional (σ1 ≥ σ2 &gg; σ3) stress regimes that produced a number of non-cylindrical folds. A D1 deformational phase produced the N–S and E–W orthogonally oriented domes and basins. The D2 arcs and synclines are oriented towards the NW and NE and indicate a clockwise rotation (35–40°) of both horizontal principal stress tensors. The extensional joints and strike-slip faults characterize the local stress field in the outer rim of the orthogonally buckled single volcanic flow, whereas the inner rim of the buckled single flow supported constriction and thus, developed the local arcuate folds.
